Love the Earth 4/5

can be broken down into earth or soil

can continue to use something for a long time

how much carbon dioxide a person's activities produce

prepare and use land for crops or gardening

when a seed begins to grow into a plant

a young tree

what comes out, especially gas or radiation

garbage that has rotted and become rich soil

when there are no more members of a species

material spread on top of soil to protect the soil and plants
